In scenarios of real-time data collection in long-term deployed Wireless Sensor Networks (WSNs), low-latency data collection and long network lifetime become key issue. We propose a Long-Lifetime and Low-Latency Data Aggregation Scheduling algorithm (L4DAS) in wireless sensor networks. Firstly, we formally formulate the problem of long-lifetime and minimum-latency aggregation scheduling as a constrained optimization problem, and then propose an approximation algorithm for this problem by constructing a degree-bounded minimum height spanning tree as aggregation tree and designing a maximum interference priority scheduling scheme to schedule the transmission of nodes in aggregation tree. Finally, through the simulation and comparisons, we prove the effectiveness of the algorithm.
